Background: This study was performed to evaluate the validity and reliability of the Kaigo-Yobo (K-Y) checklist in Korean elderly.
Methods: This study was carried on a total 283 men and women over 65 years old who visited the three community senior’s welfare centers located in Seoul and Gyeonggi province from March, 29th, 2011 to May 26th 2011. Korean frailty index (FI), Japanese K-Y checklist, cardiovascular health study frailty index (CHSFI), Activities of daily living (ADL), Korean Mini-Mental Status Examination (K-MMSE) were measured. Reliability was tested by internal consistency (Cronbach`s alpha) and the test-retest reliability at a 2-week interval. Validity was tested by Area Under Curve (AUC) from Receiver operating characteristics (ROC) curve as a predictor of frailty according to CHS criteria and the validity index estimated by the reliability index.
Results: The correlation coefficients between Korean FI and K-Y checklist, Korean FI and CHSFI, K-Y checklist and CHSFI were 0.61, 0.43 and 0.44 respectively. The ranges of Kappa value for each item of Korean FI were 0.28-0.60, for each item of K-Y checklist were 0.19-0.65. Cronbach`s alpha for Korean FI was 0.58 and for K-Y checklist was 0.64. The Area Under Curve (AUC) for Korean FI was 0.79, for K-Y checklist was 0.64. The validity indexes for the items of Korean FI ranged from 0.28-0.53 to 0.60-0.78, and for items of K-Y checklist ranged from 0.19-0.44 to 0.65-0.81.
Conclusion: The K-Y checklist is a valid and reliable instrument to measure frailty in Korean elderly. Follow-up studies are needed.
